Glossary

This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms.

administrative job	A process, executed by the Management Interface, which performs formatting and initialization
(admin job)	of the FSE media.
administrator	A system administrator who installs, configures, monitors, and maintains an FSE
(FSE administrator)	implementation.
agent	An FSE process that executes tasks on request by FSE jobs and some FSE commands. The FSE
(FSE agent)	agents are the Back End Agent and the Library Agent.
Back End Agent	An FSE agent which executes migration, recall, maintenance and recovery jobs; it also formats
(BEA)	and initializes FSE media. All read and write operations on the FSE media are handled by the
	Back End Agent. The Back End Agent process name is fse-bea.
backup	A process that creates backup image with complete and consistent state of the FSE server at a
(FSE backup)	particular point in time. The backup image can be used to recover the server in case of
	disaster. Backup image file can be located on a local or remote disk, or stored on tape media
	of the backup FSE media pool.
backup job	A specific FSE job type that executes the backup process. Backup jobs can be started by FSE
	administrator with the fsebackup command. See also ”backup (FSE backup)”.
backup log	A file that stores information about activity of the FSE backup process. FSE backup log is named
(FSE backup log)	backup.log and located in the directory /var/opt/fse/log (on Linux platform) or in the
	directory %InstallPath%\var\log (on Windows platform).
backup media pool	A special type of FSE media pool, used exclusively for backup and restore of the FSE
(backup FSE media	implementation. In contrast to regular FSE media pools, the media cartridges in the backup FSE
pool)	media pool do not contribute to the secondary storage space available to FSE users. See also
	”media pool (FSE media pool)”.
capacity disk	A disk with large storage space which stores file systems either dedicated to the FSE disk media
	or assigned to the FSE disk buffer. If used for the FSE disk media, it can be either locally
	mounted on the consolidated FSE system or FSE server, or used on a remote system which is
	accessible via CIFS or NFS protocol. If used for the FSE disk buffer, it can only be locally
	mounted on the consolidated FSE system or FSE server. Note that configurations with several
	FSE disk buffer file systems residing on the same capacity disk may reduce the performance of
	the FSE disk buffer.
check log	A file that records all the inconsistencies found by the maintenance job, which performs a File
(FSE check log)	System Catalog consistency check for a specified FSE partition. FSE check logs are named
	check_hsmfs_fsc_PartitionName (in case of the FSC vs. HSM file system consistency
	check) or check_media_fsc_PartitionName (in case of the FSC vs. FSE media
	consistency check). They are located in the directory /var/opt/fse/log (on Linux platform)
	or in the directory %InstallPath%\var\log (on Windows platform).
CIFS	The file sharing protocol used on Windows platform. This is one of the protocols used for
	accessing files on an HSM file system from a remote machine, particularly a Windows client. A
	smb server (Samba) must be running on the machine hosting the HSM file system, in order to
	allow file transfers. See also ”Samba”.
